Latest Patents

MacDonald's latest patents include methods and apparatus for imaging in conjunction with radiotherapy. These methods involve planning imaging alongside radiation treatment, allowing for the calculation of radiation doses due to planned imaging. This optimization is crucial for delivering therapeutic radiation effectively. His patents also describe the use of different characteristics in radiation beams, where an imaging beam is generated using a low-Z target, while a therapy beam utilizes a high-Z target. Additionally, imaging may be performed using a megavoltage (MV) radiotherapy treatment system, where an electron beam directed at a low-Z target generates an imaging cone beam. This cone beam can be shaped to conform to the projections of volumes of interest in a subject, and image filling techniques are employed to reduce artifacts.
